Abstract
The invention discloses a stopper lifting mechanism. The stopper lifting mechanism is arranged on a mounting plate of an intermediate tank. The stopper lifting mechanism and the mounting plate are fixed through a stopper lifting mechanism mounting wedge. A stopper mounting frame is connected with a lifting frame through a mounting frame wedge. The lifting frame is connected with a fixing frame through a driving device. A stopper mounting frame is connected to the upper portion of the lifting frame. A guide mechanism is fixed to the fixing frame. The wedges are used for fixing the stopper lifting mechanism and the mounting plate and fixing the stopper mounting frame and the lifting frame, and therefore mounting is convenient and fast. An eccentric shaft and a maintenance-free special automobile bearing are selected for the guide mechanism to be in close fit with a guide key on the lifting frame to achieve guiding, and therefore guiding precision is high, and equipment operation is stable. A scaleplate system accurately displays the relative positions of the fixing frame and the lifting frame. An internal servo electric cylinder is mounted in a fast inserted matching mode, and thus mounting is easy. The stopper lifting mechanism is compact in design and small in occupied space.
